Technical Abstract

A suction simulation device includes a suction catheter and a suction unit in fluid communication with the suction catheter. The suction unit includes a reservoir for holding fluid and the suction unit is configured to provide vacuum capability to the suction catheter. The suction simulation device also includes a pump in fluid communication with the suction unit, the pump configured to flow the fluid from the reservoir. The suction simulation device is adapted for use with a manikin comprising an airway. Also disclosed is a suction simulation system and a method of simulating a scenario requiring mechanical ventilation.

1

1. A suction simulation system, comprising: a suction simulation device, comprising: a suction catheter; a suction unit in fluid communication with the suction catheter, the suction unit comprising a reservoir for holding fluid and the suction unit configured to provide suction to the suction catheter; a pump in fluid communication with the suction unit, the pump configured to flow the fluid from the reservoir; and an endotracheal tube comprising a proximal end and a distal end, the endotracheal tube further comprising a distal end pressure transducer configured to read a pressure at the distal end of the endotracheal tube and a proximal end pressure transducer configured to read a pressure at the proximal end of the endotracheal tube, wherein the endotracheal tube is configured to be in fluid communication with the suction catheter when the suction catheter is used to remove fluid from an airway; and a breathing simulator programmed to: receive pressure readings from the distal end pressure transducer and proximal end pressure transducer; and based on the received pressure readings, cause a physical response from a manikin.
